Mitel Fax Memo Manual

							FPSA adds security in five ways. 
First, it can only be activated or deactivated by a special 
diskette, which will be shipped upon request. The person who loads the diskette (system 
superuser) is the one person who has access to the entire system. This person assigns passcodes, 
user IDS, and access privileges. There is no way to bypass the super-user passcode or to 
activate/deactivate FPSA without this diskette. 
Second, access to any part of the system (administration menus or QNX) is controlled by 
passwords and user IDS. If a password is not correct or does not match a user ID, the user cannot 
access that part of the system. Passwords only work for the assigned access privileges: if a user 
gets into billing and reporting, but doesn’t have access to configuration, that person cannot 
change FCOS, the dialing plan, or other functions within the configuration menu. This means 
that only people who are trained to perform certain functions on the system can use those 
functions. 
r. 
Third, customers can control who has access to batch commands. These are very powerful 
command strings available at the operating system level. Now batch commands can be made 
accessible only to those who are trained to use them. 
Fourth, super-users can force system administrators to change their passcodes every configurable 
number of days. This lessens the chance that hackers or outsiders will be able to enter the system 
and do damage. If an administrator/technician does not change their passcode by the specified 
date, they will be denied access to all parts of the system. 
Fifth, FPSA provides an audit trail (if the audit trail is turned on) every time an administrator 
enters the system. The trail indicates user ID, name, when the system was entered, which menu 
was entered, and what action was taken (e.g., created 200 mailboxes, changed billing rates, ran 
verify). Thus, all actions performed on the system can be traced back to a specific individual. 
9.2 Billing and Reporting 
The Series 6 system offers four categories of reports that provide comprehensive and detailed 
- information for the system administrator. 
These reports are very useful in performing billing, 
diagnostic and usage functions. The four reporting categories are: 
1. Statistics-five reports that cover how system resources are used. 
2. Billing-four reports that give a breakdown of charges for individual mailboxes, and 
calculate the total amount due. 
3. System information -ten reports that give specific information about how the system 
is configured or programmed. 
4. CDR-an optional report that tracks in detail every voice or fax call made or received 
by the Series 6 system. 
Page 29  
						

							Statistics reports offer the administrator information on usage of line ports, speech storage, 
trunks, MESA-Net, and messages. 
Billing reports give information on the breakdown of charges for individual mailboxes by 
statistic, then calculate the total amount that is due. The four reports cover current and past 
billing statistics and statistics on terminated mailboxes. 
The system information reports provide details on system configuration, classes of service, 
system errors, phone line exceptions and pager system access codes. 
Call Detail Recorder (CDR) provides a comprehensive amount of detail on all calls made to or 
from the Series 6 system. With CDR, information such as when a call was made, how long it 
lasted, whether it included a fax and, if so, how many pages, is available. CDR also records 
information on fax messages, voice messages, and pager notifications to ‘telephone numbers 
anywhere in the world. CDR is in standard ASCII text and can be exported to an off-board 
program for further editing and formatting. 
In addition to the above reports, Outdial Billing to Calling Card allows mailbox owners to be 
billed automatically for outcalls made from the Series 6 system. Both service providers and CPE 
customers have been asking for an easier, more reliable way to bill back for long distance and 
toll calls made from the Series 6 system. Long distance and toll “outcalls” made from the 
Series 6 system include off-system messaging, call placement, auto wakeup, fax retrieval and 
paging. 
With outdial billing to a calling card, all long distance and toll calls are charged to the mailbox 
owner’s calling card at the time of the call. Long distance and toll calls are defined by a new 
limits class of service (LCOS), which specifies a minimum billed outcall number length. 
Outcalls greater than or equal to this length are billed to the mailbox owner’s calling card. 
9.3 Administration by Telephone 
- Many of the system administration activities can be done over the telephone. This is quite useful 
when the administrator is away from the console or is located at some distance from the 
administrator’s work station. Functions that can be performed by phone include: 
l Creating, deleting and modifying mailboxes 
l Changing mailbox passcodes 
l Changing the system clock 
l Getting usage statistics 
Page 30  
						

							A number of security features have been added to the Series 6 system to prevent break-in and 
manipulation from the administrator’s mailbox. 
For example, the system only allows five 
seconds of response time for each prompt before it announces “no change” and returns to the 
administration menu. 
9.4 System Backup and Restore 
Frequent data backups are a very important precaution against inadvertent loss or destruction of 
data or system information files. The Series 6 system backups are easy because they can be 
performed while the system is processing calls. 
Data can be restored from floppy backups selectively or in its entirety. In the process, all 
information is restored except speech (e.g., messages and greetings). 
t 
9.5 Message Purge 
Both voice and fax messages can be purged automatically based on message age. The Series 6 
system allows administrators to define different purge limits for each of the following types of 
messages: 
l Unplayed voice messages 
l Unplayed fax messages 
l Saved voice messages 
l Saved fax messages 
l Urgent voice messages 
l Urgent fax messages 
l Voice message receipts 
l Fax message receipts 
- 
l Paging receipts 
These message retention limits may be configured systemwide or on an individua 
.l 
for maximum flexibility. 
9.6 Telnet Access 
mailbox basis 
System administrators may login to the Series 6 sener through multiple methods. First, they 
may iogin through the console using a serial port connection. Alternatively, they may dial up 
remotely using a modem into a serial port. Finally, administrators of the Series 6 system may 
administer the system through Telnet access over a TCP/IP network. The latter provides for 
faster throughput and use of existing local area networks.

							Section 10: Security 
Centigram has consistently led the industry in providing system security features at the system 
level and the mailbox level. The Series 6 platform offers a high degree of protection for system 
management, administration and maintenance, mailbox usage, and access to network facilities, 
applications and information. 
At the record level, all information and database records, regardless of format, are stored on the 
Series 6 platform in a proprietary Adaptive Digital Pulse Code Modulation (ADPCM) algorithm 
developed by Centigram. Hard disks are formatted by the factory to accept information through 
this proprietary encryption method. Additional security is provided for the database through a 
proprietary file and record format. 
At the mailbox level, the first level of security is protection through passcodes. The Series 6 
system. can be configured to require passcodes on all mailboxes. Moreover, users can be required 
to have minimum passcodes of up to 10 digits, and this can be- changed by the system 
administrator at any time to a number between 4 and 10. No trivial passcodes (simple series, 
same as mailbox number, or all same number) are allowed. If the wrong passcode is input when 
someone is trying to get into a mailbox, the cal!er must put the correct passcode in twice or the 
system will hang up. Hackers will not know if the second attempt was correct; callers are not 
prompted for the correct number of passcode digits nor are they told what was the incorrect 
entry. 
If a high number of incorrect passcodes have been attempted, the system will notify the user at 
the next login. The system also can be configured to lock a mailbox after a configurable number 
of incorrect passcodes have been entered. Only the system administrator can unlock the mailbox, 
set a new temporary passcode, reset the tutorial, and require reinitialization from the integrated 
telephone number. 
Various access limits can be applied to the Series 6 system through the Limits Class of Service 
(LCOS) to control outcalling capabilities from the mailboxes themselves. Limits can be placed 
on the number of digits that may be dialed from a mailbox (4 for in-house extensions, 7 for local 
- 
calls and 10 for paging calls to an 800 number). Limits also can be placed on an individual 
mailbox session length, causing the system to hang up when the limit is reached. This session 
limit can be lowered if a system has been threatened by hackers. 
Using RCOS, limits can be placed on the actual digits that are dialed (NPA/NXX screening) 
from a particular mailbox. 
Screening can take place at both the toll (central office) and area code 
(long distance) level. In addition, limits can be placed on the interaction between mailboxes 
through the Group Class of Service (GCOS). 
The GCOS of a particular mailbox determines if it 
may interact with any other mailbox on the system. 
For example, the GCOS could prohibit a 
messaging mailbox from accessing an audiotext one, or a mailbox on the system from accessing 
through MESA-Net a remote mailbox on the same system. 
Page 32  
						

							Enhanced security is available for all system administration functions on the Series 6 console 
through Functionally Partitioned System Administration (FPSA). FPSA allows an administrator 
to create different access privileges, user IDS and passwords for each administrator on the 
system. Moreover, FPSA provides an audit trail of all system activity and the respective 
administrator. For more information on FPSA, see section 9.1. 
10.1 Disaster Recovery 
Centigram offers multiple disaster recovery solutions. First, Centigram maintains at all times a 
stock of ready-to-ship systems in the event of a natural disaster or a major system failure. 
Second, Centigram maintains a parts depot on both the West and East coasts. Finally, using 
MESA-Net, a backup system can be configured in a different location that mirrors in every way 
the primary system. Reprogrammin 
g the switch allows mailbox owners to use the same pilot 
number to reach their mailboxes, enter their existing passwords, and hear their current name 
speech and greetings, without ever knowing that they have been moved to the remote system. 
This function is derived from the Series 6 system’s ability to broadcast messages, greetings, 
name speech and passcodes to one or more remote systems.

							Section 11: Networking 
11.1 MESA-Net 
MESA-Net provides the critical messaging tool that links the members of your team to your 
company and to your strategic partners. It links multiple Centigram Series 6 voice and fax 
servers into one, high-speed global messaging network. MESA-Net bridges geographic 
distances and time zone differences by allowing you to send messages to and receive responses 
back from your field sales organization, your sister divisions, your suppliers and your customers 
at any hour, day or night. You can send voice and fax messages to anyone or any group on the 
network from any phone or OneView-enabled PC. MESA-Net over TCP/IP is a new product 
available on the Series 6. Centigram’s MESA-Net Async product is also available in Series 6, as 
well as for Centigram systems 
running software release 5.0X. e 
Capacity to Spare 
Voice messaging systems have been effectively utilized to facilitate communications between 
people located within single buildings or campuses. MESA-Net extends your communications 
reach by networking multiple Series 6 servers into a single messaging community. Centigram 
sets a new high water mark for global messaging capacity. With Series 6 and MESA-Net you 
can provide voice and fax messaging to a large metropolitan area, a multinational Fortune 100 
company, or even a small country. MESA-Net supports links up to 1,500 Series 6 servers, 
supporting millions of users. 
High-Fidelity Messaging 
MESA-Net’s digital networking delivers high fidelity voice messaging even over noisy 
transmission lines. All messages are digitally encoded and files transferred from server to server 
with automatic error detection. 
transmissions.* There is no accumulative distortion from multiple 
MESA-Net TCP/IP, which is available in all Series 6 and above platforms, provides high-speed 
s 
message transfer between servers over standard Ethernet. Net throughput varies depending on 
the Series 6 model and other network traf3ic. 
Internet Compatible 
With the Series 6, MESA-Net can take advantage of your existing corporate network to transport 
messages from server to server using TCP/IP. 
This means MESA-Net TCPiIP is fully 
compatible with the Internet. You can use the Internet or private intemet service providers, such 
as AT&T and MCI, to connect your servers together. 
l In the initial release 6.OA the rate of transmission is only 18.5 Kbps 
Page 34  
						

							For small, very affordable configurations that have occasional network messaging, MESA-Net 
supports low-cost, dial-up modems. Depending on your messaging traffic, you can design 
your 
network to use analog lines, ISDN, 56 kbps lease lines, or El/T1 lines. 
Interoperate with Third Party Voice Mail 
Communicating with suppliers and customers is critical to any business. You can set up your 
Centigram Series 6 server to use AMIS Analog to send and receive voice messages from nearly 
all third-party voice mail platforms. In addition, to reduce toll call charges, you can use 
MESA-Net to forward your messages to the nearest Centigram system, then use AMIS to deliver 
it to the third-party voice mail platform. 
Scaleable Servers 
Centigram Series 6 servers are scaleable. You can start with a module system,supporting up to 
60 ports (2 El/T1 connections), expand it to a 4-module system, and then network multiple 
systems together using MESA-Net to support up to 360,000 ports. Depending on the level of 
network message traffic and the number of servers supported, you can use a 10 Mbps Ethernet 
LAN to deliver up to 20,000 network voice messages per day (assuming 30 seconds/message, 
18.3 kbps speech encoding). 
Minimize Networking Costs 
In some cases, Centigram Series 6 servers will be connected via dialup lines (e.g., POTS, 
switched 56, or ISDN). To effectively minimize the cost of network charges, each Series 6 
system can be configured to accumulate messages in a queue until a certain threshold is 
exceeded, and then send all the accumulated messages at once across the network to their final 
destination. Different types of thresholds include: number of messages in queue, cumulative 
number of minutes messages have waited, total length of messages waiting, or time of day. 
System managers can set each of these thresholds to optimize the balance between cost and 
delivery delays. 
There also are separate queues for normal and urgent delivery messages. The administrator can 
set lower thresholds for urgent messages, allowing them to get delivered faster. The sender has 
the option of marking their message urgent or normal. Records are kept on all network messages 
so appropriate billing or cost allocations can be performed. 
Upgrading Basic MESA-Net Networks 
Series 6 systems can support both MESA-Net TCP/IP and Async MESA-Net. The Ethernet card 
and the serial (RS232) card must be installed in separate modules. Network message throughput 
between high-traffic locations can be improved by replacing existing Async MESA-Net 
networks with a TCP/IP network. Series 6 servers must maintain a hybrid MESA-Net TCP/IP 
and basic network configuration until every node has been upgraded to TCP/IP.

							MESA-Net Specifications 
Series 6 servers support one Ethernet 1OBaseT interface and up to 32 WS-232 asynchronous 
ports. MESA-Net TCP/IP is intended for use with existing corporate wide area networks 
(WANs) or for connecting several collocated Series 6 severs together.

11.2 AMIS 
AMIS Analog is a Series 6 system networking application that allows Series 6 systems to 
communicate with other vendors’ voice mail systems. With this optional feature installed, 
mailbox owners can send messages, receive messages, and answer messages received from 
remote systems. 
Any mailbox owner who has AMIS Analog can make and give messages from the local system 
to any other systems equipped with AMIS Analog capabilities. Any message that cannot be 
delivered will be returned to the message maker with a reason for nondelivery. When a message 
is received from another system, the mailbox owner may answer that message with a single 
keystroke. 
Centigram offers AMIS Analog to send and receive voice messages from &arly all third-party 
voice mail servers. You can transfer your message via MESA-Net over your low-cost network to 
a nearby Centigram system and then deliver it to the recipient’s voice server over AMIS. 
Centigram has enhanced AMIS Analog in Series 6 to provide the same universal dialing plan 
capabilities provided by MESA-Net.

							Section 12: Switch Integrations . . 
Switch integrations establish a connection between a telephone switch and the Series 6 system. 
This connection provides call information for direct or forwarded calls and message waiting 
signals for the user, and is transparent to both callers and users. When the telephone switch and 
the Series 6 system are integrated, the two systems interact to give capabilities that neither 
system could provide alone. For example, an outside caller is automatically forwarded to the 
personal greeting of the called party, instead of reaching the main greeting and having to re-enter 
the party’s extension. In addition, a caller can return to an operator after reaching voice mail, 
without having to hang up and redial. 
The Series 6 system uses three different methods to integrate with a customer’s private branch 
exchange (PBX) or central office: call in-band DTMF, direct data link, and electronic set 
emulation. The Series 6 platform also supports two additional integrations with telephone 
switching networks: R2 and SS7. 
12.1 PBX Integrations 
l Call In-band DTMF and MF- where the switching system and the Series 6 system 
communicate with one another using an exchange of tones in the voice frequency 
band (inband). 
l Direct Data Link-where the switching system and the Series 6 system communicate 
with one another using a special data communications circuit, separate from the voice 
channel. 
l Electronic Set Emulation-where the Series 6 system acts as an electronic telephone 
within the switching system. The Series 6 system extracts and presents call-related 
information as if it were a station. 
12.2 R2 Integration 
Through its R2 integration module, the Series 6 platform provides the interface link between 
telephone networks and the Series 6 system. The R2 module converts R2 Channel Associated 
Signaling on 30-channel PCM (El) trunks (CCITT Rec. G.704) to the Series 6 platform’s 
gromietary analog signaling. It also converts the Series 6 system’s analog signals back to the R2 
protocol digital signaling for the telephone networks. It demultiplexes and decodes incoming 
PCM voice lines and encodes, multiplexes, and frames outgoing messages from the Series 6 
system into the El format. Centigram’s R2 integration module conforms to CCITT Q.400, 
Q-421,4.440, and 4.441, Fascicle VI.4, supplement no. 7.
